The object of our present invention is to provide means for generating'ozone in comniereal quantities at acompz'tratively `small evident thatany suitable source of. electricalsupply may be utilized and thatany'current of a sufficiently high voltage may-be passed through Vthegenerator, the-connection of the generator. to the sourceoli-:electrical supply depending of course upon'the conditions and.material at'hau'd'. vAssociated .with thefgeivso crater A is a suitabledevice 'aay'bymeans of which the oxygen or air-is passed through thegiterator.v It is of course evidentfzthat `anysuitable arrangement forth rs1-purpose niay utilized. 4-

other set, C, boing. connected with the other branch of the circuit,thus making the electrodes li of opposite polarity'tdthe electrodes C.Said electrodes maybe made of any suitable conducting material and, asherein illustratcd, consist of copper wires which project from the endsof the tubes and which are wrapped one about the otheiqsothat they willall be electrically connected together. This method of forming'the-electrodes is cheap, durable, and eicient. In the operation of ourdevice we prefer to use an alternating current of comparatively highvoltage, .the Voltage ldepending of course upon the construction of thegenerator and the conditions 'to be'met. 'lhe'electodes B and C arecomlt isof course evident that any` and that suchmateral may be formedand l disposed in anysuitable manner. For pur- `poses of illustration wehave shown this non-g conducting material B' C.' as consist-ingofcomparatively small tubos of glass or other material, into which theelectrodes are inserted.1

These tubes are "providedwith a -suitable sup-- port, .by means oflwhich :they are supported in proximity to cach other.; the 4severaltubes.`

bein-g separate'dby suitable air-spaces.l The several conductors ;are.'alsofy insulated from p each other in seme 'suitable-:niann-enso as toprevent the? destructive discharge f the eurrent frolntheposi-tivetofthe; negative elcctrodcs.` A's illustrated in' lthe."dra.wings,'.` wc

ports B2 end C with openings which extend only part wey therethrough toreceive the ends of the tubes, es shown Ain Fig. 5, we securely insulateone set of electrodes from the other, and by lling the tubes port weywith insulating materiel, such as sealing-'wem as illustrated inl saidfigure, we secure a. better insulated construction and also prevent thedestructive action of the ozone on the active wires in the tubes. It isof course. evident that this construction may be varied in any suitablemanner and I:het the insulation of' the several ports may be broughtabout by any suitable means. The electrodes are preferebly arranged sothat they-will be alternating positive and negative an are preferably sopositioned es to be e uniform distence apart throughout their length, soes to pre vent any evil effect-such, for exemple, es a. spark-discharge,which. might he brought .Ewout by having come portions of theele'ctrodes closer to each other than other porf tions.v It will be seenthat by this construction the electrodes are completely surrounded byinsulating materiel end in additionY are insulated by sir-spaces betweenthe surrounding pieces of insulating materiel. The electrodes C and Bere-connected in circuit in any suitable manner. As shown in thedrawings, the electrodes C, for example, ere connected together, esyindicuted in Fig. 4,

and ere all connected to a. conductor D, which passes through en openingD' in the casing which surrounds the electrodes. The electrodes B areconnected 'together in u similar manner end are connected tothe'conductor D, which passes through en opening D in thev inclosing boxor casing. Any suitable inclosing device may be used, und such iuclosingdevice is preferably mede of non-infsuleting materiel, preferably herdrubber.- The supports Ba end Cf* divide the interior of the casingintothree apartments. The ozone is formed in the control apartment, and thetwo outer apartments-nre entirely separated ments, the elements beingsupported uponfa;

'h en insulating-tube two supports igity to auch other, between whichscid usuconnect'the electrodes' B und G with a suit'4 able'source ofelectric supply, a compara# tively highvoltuge alternating current beingpreferably used. When the electrodes are connected in circuit, esilentor brush discharge, an it were, occurs between the elec-l trodes ofopposite nolerity, the voltage of the current being regulated so as toproduce this result. This brushdischargecauses the air between theelectrodes to assume a bluish tinge, as it were', and is distinguishedfrom the illumination or spark which occurs when o spark-discharge takesplace. .Air or oxygen, either alone or mixedf with other gases, ispassed through the generator, and by means of this silent or brushdischarge We produce l what is commonly 'termed ozone We lieve found.that by means of this coustruction the ordinaryetmosphlereor ir may bepassed et e comparatively repi-d rete through the generator, e portionof the er being quickly coverted into ozone. It will therefore be seenthot we have hereacheap, ecient, and commercially successful device forconverting-oxygen into ozone in commerciel quantities. Any suitabledevice fonmoving the oxygen or'uir or the like through the generatorinay be used-such, vfor example, es e. pump vor feu-.end we have foundthat when e'r is passed through our generator it is converted into ozonelof e comparatively v pu re quality unmixed with undesirable gases.

Our generator muy be used for any desired For example, it may be used togenerate ozone for antiseptic purposes or for. commercial use in ny ofthe elds where the use oi vozone or an antiseptic or' serilizing ugentmoy be beneficial.

We hevedescribed 1u deteilvn. particular -conetruction of our device forzpurpofilee-of illustration, but we wish it to lne-understood the-t we'in nov manner limitoureclves tothe construction shown, es the devicemaybe-varieti in form, construction, and arrangement without departingfrom the spirit of our 1nvention. Tie nu mber of Aelectrodes and their'.arrangement anddistuncev4 `eport may', of

course, be varied in accordance with the'con ditions to be. met. i v-Byproviding two chambers for the connect ing-wires, which are separatedfrom the cnam- V ber in which the ozone is generated andiolso from thechamber into which the ozone 1s d1a cherged', it wirllbe seen 1tzlgtfthe connecting-l wir are ent rotec rom'- es y p As the insulation of'these connecting-wires is injured or removed at the points of connectionrt will be seen that some suitable protection is necessary. n
